So I have two reos. one with the new adjustable 510 and one with the old style 510. The one with the old 510 leaks very bad every now and then. usually my center feed tube has come loose where it screws on and holds the firing pin in place. When that happens i just take it apart, clean it out and put it back together making sure the center pin is screwed on tightly. This time it leaked all over the inside of my mod but the center center feed tube is still nice and tight like it should be. I always thought the center feed tube being loose was the problem and it probably was. But with the center feed tube still tight this time what else could be causing it to leak all over the inside? I know that sending it to Rob for a 510 upgrade would most likely solve the problem but i just cant afford it right now... Any suggestions would be greatly appreciated.
